The Lowdown
Alright, I’m lookin’ through the 16-day window here and, honestly, I gotta be straight with you – there’s not a whole lot worth paddling out for. We’ve got a long stretch of really weak, messy conditions, and it’s gonna take quite a while before anything even remotely interesting shows up.
The first real chance for surf doesn’t come until much later, so we’re looking at a big gap of nearly two weeks with nothing on the cards. The first record of anything surfable is on the 27th of August, and that’s a long way off.
Kennebunk Beach (Maine, USA) is the only spot in the mix, and for the first couple of weeks, it’s a ghost town. From Wednesday the 12th right through to Wednesday the 26th, it’s all poor surf conditions – tiny swell, mostly under 2 feet, and the wind is all over the place. There’s some light, clean moments on the 15th and 17th with a bit of cross-offshore, but the swell is barely a ripple, so it’s not worth getting wet for. The water temp on the 12th is 69°F, which is a touch warmer than usual for this time of year, but that’s about the only highlight.
Now, come Thursday the 27th of August, things finally perk up. The morning sees a 5 ft swell from the ESE with a period of 8 seconds, and the combined energy hits 323 (moderate wave energy). The wind is light and offshore from the NE, keeping it clean. The afternoon holds steady at 5 ft from the same direction, also clean with a light cross-offshore breeze. It’s still not a standout day by any means – the period is short, so those waves will be a bit weak and crumbly, and the break is sheltered, so it won’t be packing much punch. It’s surfable, but very ordinary. This is honestly the best on offer, and it’s only for the experienced heads who are desperate. For the rest of us, it’s still a wait-and-see game.

Information about the Kennebunk Beach Surf forecast
The above surf forecast table for Kennebunk Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Kennebunk Beach can be found by selecting the local surf guide option on the grey menu. Our Kennebunk Beach surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Kennebunk Beach) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Kennebunk Beach may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
